IMPROVEMENT lN GRAIN-REGISTERS.

Specification forming part of Letters Patent No. 179,136, dated June 27,1876; application filed October 22, 1875.

To all whom it may concern:

Be it known that I,1\/IICHAEL SHAWVER, ot' the county of Clarke andState of Ohio, have invented certain Improvements in Tallying- Machinesor Grain-Registers, of which the following is a specification:

My invention relates to that class of tallying-machines orgrain-registers which are attached to thrashing-machines for the purposeof registering the number of bushels of grain or seed thrashed andmeasured as it passes through them.

My invention has for its object simplicity of construction, cheapnessofcost, ease of operation and attachment to the thrasher, and eertainty incorrect registry, also facility for recommencing.

A small wooden case incloses the mechanism, which is operated by aswitch-gate in an inclined spout passing under it. Two dialplates areseen upon the front of the case, one of which shows the number of halfbushels of grain thrashed up to ten, while the other gives the number inhundreds.

Figure l is a front view of my improved tallying-machine. A portion ofthe face (in eluding part of the dial-plate) is shown broken or cut awayto exhibit the interior mechanism.

A is the case, which is attached to the side ofthe thrashing-machine,its base resting upon the grain-spout D, which forms a part of thedevice. A (the great wheel) registers the number of bushels by hundredsupon the dial in front of it. B is a smaller wheel, having larger teeth,and asingle-toothed pinion, G, on its shaft, (under the small dial,)which meshes into the teeth of wheel A. O is a singletoothed wheel,which turns only partially around, so as to impinge against the teeth ofwheel B, rebounding after each contact, and moving B one tooth eachtime. It has a cranklever, K, on the front end of its shaft, which isconnected, by the small link or lever c, to the latch-lever Z. Thelatter extends across the spout D, being pivoted at its right end to thebase of case A. ltis made thickest in the middle, forming an obtuseangle on its lower edge, so as to allow it to rise up when operated uponby the switch-gate E, passing under it from side to side. The latter ispivoted by its lower end in the middle of the open end of spout D. It ismade of board, setin edgewise the same depth of the spout, and extendsback un'der thelatch-lever l, as shown in the figure.

Both wheels A and B are provided with retaining-pawls, mounted uponsprings. That of 1) projects downward from the upper left corner of caseA, and meshes into the teeth of wheel A. The lower end of this pawl isprolonged, so as to be operated upon by the upper end of the reactionarylever c, which is pivoted upon a pin at its middle part, so that whenits lower end is pushed in by the loose stud b, (which passes at thispointthrongh the case, its head projecting outside,) its upper end,lapping behind the prolonged end of pawl 19, throws it out of gear withthe wheel.

vThe object of this device is to allow the; wheel A to be turnedbackward with its index to the point of beginning, when it is desired torecommence tallying.

In operating the machine the index-hands are first set at zero, thethrasher set in motion, and the grain passes through the spout D fromrear to front from the conveyers. Two half-bushels are provided, and assoon as one is filled the switch-gate E is switched to the opposite sideof the spout, cutting off the stream of grain and directing itinto theother half-bushel. the latch l, and the connecting or link lever cpushes up crank-lever 70, attached to the shaft of the reboundingsingle-toothed wheel 0, which turns to the right until its tooth movesthe wheel B one notch, raising pawl 19, (which falls into the nextnotch,) and the index on the small dial marks one tally, or onehalfbushel. The gate is then switched to the opposite side, marking asbefore, the wheel 0 rebounding after each movement. When wheel B hasmade one revolution and marked ten tallies, the single-toothed wheel 0catches one of the teeth of wheel A, raising its retainingpawl 0, andmoving it one notch.

The teeth of the wheels and their pawls are all V-shaped-z'. 6., theirfaces have equal angles, and are beveled to an edge-as othershaped teethwould not operate in the same manner with the single-toothed wheel 0.

The shaft of the great wheel A should be extended out of the back of thecase, orit may be provided with a post for a key, by which it Themovement of gate E raises can be turned backward in beginning, when thepawl 9 is raised by the lever 0 with stud I). To lessen the cost ofconstruction, I make the wheels and pawls of wood, hard wood beingpreferable. Any ordinary mechanic can construct the device.

The Front of the case is entirely tight, and the whole is excluded fromdust, and from being tampered with, by inclosing it in an airtight box,which is readily attached to the thrasher.

I am aware that tallying-machines registering by cloclrgearing are notnew, and I do not wish to be understood as claiming the same as any partof my improvement.

In all ordinary registers or tallying-machines, where the movement istransmitted from a cut-01f valve or switch-gate to the gearing, thetooth, pin, or cog, or other projection, after contact with the tooth ofthe wheel which marks the tally, passes by said tooth, either in full orpartial rotation of said pin or cog.

not claim it; but the rebounding single-toothed wheel 0, by which themachine is operated, as well as the lever 0, with its operative stud I),in combination with the pawl p and the gearing shown, I believe to benew.

Such movement is old, and I do' I therefore claim- 1. In eombinatiom ina grain-register or tallying-machine, having a case, A, provided withtwo graduated dials and wheels, A and B, having teeth with equal angles,(the latter with its single-toothed wheel 0, mounted on the same shaft,)and their respective retaining-pawls p and 19, constructed as specified,the rebounding single-toothed wheel 0 its connecting-lever c,crank-lever 7c, latch l,

switch-gate E, and spout D, as and for the MICHAEL SHAWVER. Attest:
